I unwittingly disabled my Chromium host Executable not realizing that was needed for my Autodesk Desktop app, I think it may have affected the license registry, when I try to fire up 3DSMAX 2018 it blinks momentarily, then disappears not initializing, I put an ~ sign in front of the acwebbrowser.exe because I saw an alarming amount of its propagation in the task manager, copied the original else where just in case, but when I went to check on it, my change didn`t take affect, the .exe was still named properly, so i rebooted, and it still wouldn`t initialize the spalsh screen blinks quickly and goes away without an error message, thanks for your time.
